I wasn't explicit enough in my request. The above works fine (another 
TLUGer suggested it by email), but what I really want is a message saying: 
"the `bah' portion of the manifest needs updating, etc ."

(Sam Tilder's suggestion probably works too, but the result would be the 
same as the above, AFAICT.)

O K !  I have it:

manifest: foo.mk bah.mk bletch.mk

bah.mk: bah
        @example.com bah.mk
        @example.com "Need to update 'manifest' with bah!"
foo.mk: foo
        @example.com foo.mk
        @example.com "Need to update 'manifest' with foo!"
bletch.mk: bletch
        @example.com bletch.mk
        @example.com "Need to update 'manifest' with bletch!"

Hmmmm. Works OK, but only once. I guess I could do the `touching' in another
script.

Thanks

Jim
